Aylin went to the store to buy some new folders for school . She bought a total of 7 folders and spent a total of $12. She bought two different types of folders. Plain folders that cost $1 each and folders with cartoons that cost $2 each. How many did each type of folder did Aylin buy?
Answer:
2 plain folders and 7 folders with cartoons
Step-by-step explanation:
Given data
Let the number of plain folders be x
and the number of folders with cartoons be y
x+y=7------------1
x+2y=12----------2
from 1
x= 7-y
put this in 2
7-y+2y=12
7+y= 12
y= 12-7
y=5
Put y=5 in 1
x+5= 7
x= 7-5
x= 2
Hence Ayin bought 2 plain folders and 7 folders with cartoons

Evaluate x + 23
when x=7
Answer:
30
Step-by-step explanation:

Answer:
< F would be 140 degrees
Step-by-step explanation:
So what you would do is that since they told you angle D is 40 degrees and you know that the 2 lines in there are parallel, and since they are asking for angle F, whne you add angle F and angle H they should equal 180 degrees which you know so you just subtract 40 degrees from 180 and you get 140 degrees which if angle F and you can subtract 40 since angle H and angle D would be congruent.

What is the slope of the line?
Answer: Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m.
Step-by-step explanation:
Answer:
slope = [tex]\frac{7}{4}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, - 3) and (x₂, y₂ ) = (3, 4) ← 2 points on the line
m = [tex]\frac{4-(-3)}{3-(-1)}[/tex] = [tex]\frac{4+3}{3+1}[/tex] = [tex]\frac{7}{4}[/tex]
